NOVELTY - Self-supporting flexible hydrogen peroxide sensor electrode material based on manganese oxide-cobalt/reduced graphene oxide-carbon nanotube (MnO2-Co/rGO-CNT), comprises 3D porous nano-flower-shaped MnO2 and a diameter of about 120 nm. The surface convex-concave nano-spherical Co in-situ grows on the rGO-CNT film to form self-supporting flexible hydrogen peroxide sensor electrode material. The preparation method is: taking self-supporting flexible composite film rGO-CNT as working electrode, Ag/AgCl electrode as reference electrode, electrically depositing for 300-1000 seconds, washing with deionized water and then drying at room temperature to obtain MnO2/rGO-CNT, taking the obtained MnO2/rGO-CNT as working electrode using constant potential method, selecting the deposition potential is -1.05V to -1.45 V, electrically depositing for 38-180 seconds, cleaning with deionized water and drying at room temperature. USE - Self-supporting flexible hydrogen peroxide sensor electrode material based on manganese oxide-cobalt/reduced graphene oxide-carbon nanotube used in health medical monitoring, human body movement monitoring and artificial intelligence. ADVANTAGE - The electrode material has excellent anti-deformation ability, wide detection range, low detection limit, high sensitivity, good selectivity and high stability.
